FOLDING BED.

Application led January 27,1925. SerialNo. 5,123.

This invention relates to beds, and especially to foldable or collapsible beds and camp beds.

An object of this invention is to provide a collapsible metal structure bed which, while it may be `very compactly folded into a small space, can be easily unfolded, eX- .tended and set up in a very short period of time. An object is toY provide a knock-down bed incorporating a means whereby a mattress spring fabric maybe highly tensioned .between endbars of the bedframe sothat thev spring will-be capable of. comfortably supporting two. or .more persons,A and vyet en- .ablingthe tensioning tozbelperformed by womanor. child of average strength.

.An objectis. to provide a camp bed which, while having elements of low cost of manufacture and of simple fori-n, provides for durability, strength and safety.

An object' is .to Iprovide a foldable camp bed of ,obvious mechanical manipulation enabling anyone of..-orclinary.. ability to unpack', extend .and fully set upthe bed with ease.

.Another object is toprovide a noveland .substantial foldable and locking brace for relatively foldable elements.

Gtherobjects and advantages will jbeinade .manifest Vin the .followingspeciiication of apparatus embodying one forml of the invention illustrated in the Haccompanying drawing; it being understood .that modiications, variationsand adaptations may be resorted to within the spirit ofthe invention .and the scope thereof as. here claimed.

.An object of the inventionis to provide .an elongated hook-link 6.

V21 to receive a fixed pin 22.

as few'fu'lly detached elements as practical in the provision of a substantial Vand readily adjustable bed.

.As shown, the bed includes a pair o'f duplicate side rails each having a pair ofchannel-iron sections 28, which areinternest- .able,.asshown in Fig. 7, in a collapsed po- VSition, and -arepivotally att-ached on f1-pivot .4 to unfoldin alignment. ThesectionV 21 has buda-.single hole forthe pivot pin l," but section Bhas aplurality of'pin holes'5 so .that the effective length of the extended. rail may be varied'for a purposelater mentioned.

`Also mounted 4.upon pivot L.L-of ara-il is A tensioning brace including a member' '7 is also ,mounted ont pivot pin 4. V.This brace has an intermediatev lever arm 8 pivoted at 9 on the-swinging Vend of member 7 and the projecting short arm 8rL of the lever 8 is attached at lO 4to the rear end of .a hook 1l. The'lever 8,

when swung away from the link 7, pulls in the hook ll and the composite brace 7-8-11 can then ,be dropped into the rail section 3. The hook-link 6 can also be folded down into the section 3, and then thesection 2 can befolded into the section 3, as in"Fig.'.7.

Sections 2V of the rails havehook slots 2a and sect-ions 3 have straight slots Bin the ends. IEach rail 'forms a c0mplete,finter v ground preparatory to setting up the bed,

asin Fig. 2.

Along the inner face of the otherfiange of the stile l5 are provided pivots 17 carrying the upper ends .of stout. legs 18, capable of being folded into alignment along the stile. A spacer 19' holds the leg 18 .slightly from the flange of the stile and in the plane of the spacer is a floating link k20 slotted at The swinging end of link 20 is attached to a link 23 which is connected to a pivot 24 in a leg 18. A pivot pin 25 connecting links 20-23, eX- tends at 25a to form a strong bolt or latch to snap into a hole 26 provided in the stile iiange. The purpose of the slot 21 is to allow the bolt to be shifted until it finds its way into the bolt hole 26, thus facilitating locking up the leg as in Fig. 3. This form of locking brace is highly eiiicient and safe.

It cannot unfold beyond the limit of the aligned links 20-28 and if the bolt-pin 25 is not set in its hole 26, the link 23 will swing up against the top flange of the stile and so hold the leg fro-m inward collapse. Fig. 7 clearly shows the intermediate and internested rail members and their enclosed hook-links and tension braces, the stacked folds of the support S, and the end stiles 15 as lying in a carton C, shown in dotted lines. To set up the bed it is taken from the carton and the rails are lifted from the stack of web folds F. Then the legs 18 of the upper stile are unfolded and locked and stood upright while the hook-slot end of one of the rails is slipped into a leg; these being here shown as of channel-iron, and hooked down over a .fixed bar 27 in the leg. Preferably the rail sections are unfolded before they are hooked to the first set up legs. The second rail is then in a similar manner hooked to the other leg. The hook .links 6 are passed down over lower bars 29 in the legs and the far ends of the rails are rested on the iioor or ground while the remaining, free stile is pulled up over the set up end of the bed. The second stile is shifted along the rails to the far end and then its legs 18 are unfolded and locked by bolt- 25. One leg is now hooked by bar 28 in slot 8a in the near rail end; the fabric being Slack. The first hook-link 11 is now extended by hand-lever 8 to pass over a lower bar 29, and the leg is now pulled in at the bottom and thrown out at its top, thus placing its side of the fabric S under tension, as in Fig. 1. The pulling in of the bottom of the leg is accomplished by pulling hand-lever 8 around over the hook-link 11, effecting a shortening of the tension device 7-8-11- This leaves the other side of the fabric slack as is indicated by dotted line L. The second tension device is now extended by its handle 8 until its hook 11 engages the lowerl bar 29 in the near leg; the slotted rail end being hung on the upper bar 28 in the leg. The hand-lever 8 is then thrown around over its hook 11 with a firm pressure which draws in theV last leg 18 and straightens it up to strongly tension the fabric S.

By actual demonstration, the tensioned fabric is found to supportl three adults of average size without undue sagging.

Any desired means may be employed to secure the tension-brace parts 8-11 in contracted position. This means may include a simple L- or Thead pin or screw 31 on one of the parts to pass through a slot in the other part and then be turned across the slot and be held in interlocking position.

To shorten or lengthen the rails, the pins i are placed in the desired holes 5 of the series in the rail sections 3.

An important feature of the invention is that the bed can be lengthened by shifting the sections 8 and their braces 8-11 by simply inserting the pins Li in the desired holes 5 of the sections 8. TWhen the braces 8-11 are clamped to tighten up the fabric S the legs 15 are always brought perpendicular to rail sections 8. The springs 16 allow for shortening or lengthening of the rails without tilting of the legs on the ends of the sections 3. Lengthening the rails, increases spring tension but does not change the angle of the legs.

1. A collapsible bed including a pair of foldable side rails, rigid end stiles having pivoted legs, a mattress support connecting the stiles, means for detachably connecting the legs to the ends of the rails, rigid, c0ntractable and extensible support tensioning means including levers connected to the lower ends of the legs and to the rails.
